Panasonic's concept of connecting 6 sets of Sensor heads to 1 Controller in series offers maximum flexibility to solve a wide range of safety applications. Just configure exactly the number of Sensor heads and controllers required to protect the area in question, e.g. small openings or irregularly shaped spaces impractical for Safety Light Curtains. A beam interruption indicator is incorporated in both the emitter and receiver to indicate operation and assist with beam alignment.
The high-functional Controller, ST4-C12EX, can immediately diagnose misaligned or abnormal Sensor heads. Its digital display shows errors immediately and supports both PNP and NPN polarities.
